  • Question
  • What is the result of segmenting a network with a bridge (switch)?

    1. It increases the number of collision domains.
    2. It decreases the number of collision domains.
    3. It increases the number of broadcast domains.
    4. It decreases the number of broadcast domains.
    5. It makes smaller collision domains.
    6. It makes larger collision domains.


  • Options
  • A. 1 and 5
  • B. 2, 3 and 5
  • C. 3, 4 and 6
  • D. 1, 3 and 6

  • Correct Answer
  • 1 and 5 

    Explanation
    Bridges break up collision domains, which would increase the number of collision domains in a network and also make smaller collision domains.
